United States Patent 3,194,527 BRACKET Jack Gross, 2710 Emmet Road,Silver Spring, Md. Filed Apr. 1, 1963, Ser. No. 269,244 3 Claims. (Cl.248-435) The present invention relates to brackets which can be used asa support such as a shelf-bracket or can be used as a brace betweenframing members and the like.

The primary object of the present invention is to provide a bracket ofimproved strength by using the anticlastic surface of the hyperbolicparabolcid in distributing the forces applied to the bracket.

Further objects of the present invention are to provide a light weightbracket formed of a single sheet of material, inexpensive tomanufacture, and having a high degree of strength.

Further objects and advantages of the present invention will be readilyapparent from the following detailed description taken in conjunctionwith the accompanying drawing wherein:

FIGURE 1 is an isometric view of the bracket forming the subject matterof the present invention.

FIGURE 2 is a side view of the bracket of FIGURE 1 illustrating the useof the bracket as a shelf support.

FIGURE 3 is an isometric view of the bracket of FIG- URE 1 illustratingthe use of the bracket as a reinforcing brace, and

FIGURE 4 is a side view of a modified form of bracket used as anexternal brace.

FIGURE 5 is a horizontal sectional view of the bracket in the positionshown in FIGURE 3.

FIGURE 6 is a vertical sectional view of the bracket in the positionshown in FIGURE 3.

Referring to the drawing in detail and particularly to FIGURES l, 2 and3, the bracket forming the subject matter of the present invention isgenerally indicated by numeral 10. The bracket may be made of metal orequivalent material and is shaped to the form disclosed from a singlesheet of material. The body portion of the bracket, indicated by numeral11, comprises the surface of a hyperbolic paraboloid, said surfaceterminating at its edge in a flattened surface 12 for attachment to asupport. The flattened surface 12 is provided with a plurality ofopenings 13 for receiving screws or the like for anchoring the bracketto a support.

FIGURE 2 illustrates the use of the bracket as a shelfsupporting bracketbetween a vertical Wall 15 and a shelf member 16. In this form of use,the bracket may be considered as being in vertical position. The samebracket when turned on its side or in horizontal position serves I as abrace between framing members 17 and 18.

As seen in FIGURE 1, the flattened surface 12 which extends completelyaround the body portion 11, comice prises a pair of substantiallyV-shaped sections with the numeral 19 indicating the apex of the V, saidsections being joined to each other at right angles to each other withthe apex of the angle being indicated by numeral 29. Thus, as viewed inFIGURE 2, with the bracket in vertical position, a vertical sectiontaken through points 19 will define a hyperbolic curve and a transversesection taken through points 26 will define a parabolic curve. In FIGURE3 the bracket is identical with the bracket shown in FIGURE 2 exceptthat it is turned and used in a horizontal position as a bracing member.

FIGURE 4 discloses a slightly modified form of bracket wherein the bodyportion 11' terminates in a flattened surface 12' defining sections 21and 22 which instead of being at right angles to each other, define anangle of Thus, a pair of brackets as shown in this figure, can be usedas an external brace between members 23 and 24. The two brackets aresecured to each other by means of bolts 25 and to members 23 and 24 byscrews 14. It will be understood that the angle between sections 21 and22 may vary depending upon the angle between members: 23 and 24.

it will thus be apparent that the present invention is well adapted toaccomplish the objects and advantages set forth. It will be understoodthat minor changes may be made in the details of construction withoutdeparting from the spirit and scope of the invention except as may berequired by the appended claims.

What is claimed as new is: V 1. A bracket comprising a hollow curvedbody portion terminating in a flattened portion defining a pair ofsubstantially V-shaped sections, each of said sections being angularlydisposed with respect to the other of said sections for securement to asurface, said bracket when used in a vertical position being so shapedthat a vertical section through the body portion thereof defines ahyperbolic curve and a horizontal section through the body portiondefines a parabolic curve, said body portion having an outer surface inthe form of a hyperbolic paraboloid.

2. A bracket as defined in claim 1, said flattened portion comprisingtwo sections at right angles to each other.

3. A bracket as defined in claim I, said flattened portion comprisingtwo sections at an angle of 135 to each other.
